Former Gov. Rod Blagojevich's brother wants to testify before the U.S. House Committee on Ethics investigating whether an Illinois congressman sought to raise money for Blagojevich for an appointment to President Barack Obama's old Senate seat.
Robert Blagojevich tells Thursday's Chicago Sun-Times he's written to committee members offering testimony about Democrat Jesse Jackson Jr.
Rod Blagojevich was convicted of trying to sell Obama's seat. Related charges Robert once faced were dropped.
Trial witnesses alleged Jackson supporters offered fundraising for the governor if Jackson became senator.
Jackson's denied wrongdoing and hasn't been charged. He testified at Blagojevich's retrial that he's "never directed anyone to raise money for another politician." His spokesman declined comment Thursday.
But Robert Blagojevich says "there are a lot of unanswered questions (Jackson) should be required to answer."
